Problem 1 (20 points): A heat engine receives 700 kJ from a heat source at 500 K and rejects heat to the surrounding air at 27°C. The work output from this engine at steady state operation is 200 kJ. a) Sketch the system described in the problem statement. On the sketch, identify the high temperature reservoir, the low temperature reservoir, and all the energy transfer mechanisms relevant to the problem. b) Calculate the maximum efficiency at which this engine could operate. c) Calculate the heat rejected by the engine to the surrounding air under steady state operation. 410 1:00 and
